The Application of Blockchain in Intelligent Power Data Exchange

The State Grid ETL(SG-ETL) tool, based on Extract, Transform and Load(ETL) technology, has important application value in intelligent power data exchange. As an important part of the transmission component in the power grid system, it realizes the data exchange between power systems, but in the process of data exchange, problems are gradually exposed such as unguaranteed data quality and uncontrolled business process. In this respect, this thesis studies the blockchain technology and analyzes its feasibility in the application of intelligent power data exchange, optimizes the power transaction order management business process from the blockchain perspective as example, proposes the Decentralized Transaction credit model based on Blockchain P2P(DTBP) according to the process, and describes its evaluation algorithm, introduces the idea of "chain on the chain" to plan the scheme of data to chain in the data exchange process, designs the smart contract life cycle, formulates contract rules and interface function conventions, uses the JSPIN tool to design the third convention's Promela mode, verifies the data and analyse the result to solve the data exchange problems finally.
